Dealing with airstart igniters
In a reply to my own thread on hybrid vent tubes, I asked this question but got no response, so here I am starting another new thread specifically for this topic.
When setting up an airstarted motor, how do people make the connections to the igniters? They have to be secure enough to maintain continuity during takeoff and at speed, but they shouldn't be strong enough for the igniters to keep hanging off the rocket once the airstarts light. They should be at least somewhat easily replaceable, or so I would think.
For my next planned rocket, this is a tough issue. The rocket has a 38mm central tube which can't have wires routed through it. (Treat it like it has a 38mm motor inside.) The two airstarted 29mm boosters will be in minimum diameter pods fixed to either side of the central tube, with an altimeter in one of them ahead of the motor.
How do I make the electrical connections to the airstarts in an aerodynamic, lightweight, secure, yet impermanent connection? I don't want too much thickness, though I'm not averse to putting a slightly bulkier connection in the valley between the pods and the central tube as long as it's aerodynamically symmetrical and not too heavy.
I'd like to hear both about what you people have done on your rockets, whether it's applicable to mine or not, and what people would suggest that I do. Just spit out any crazy ideas you have; I will make them work if I have to. I can do the specific designing; I just need your experience guiding me to make this happen.
